(TYPO3 4.0.5,PHP 5.1.6 -> both being upgraded today). My site is
multilingual and I always upgrade extensions by default. I also clear all
cache at the start of each day manually...

displayed normally but with that annoying reference, but I DO NOT want to be
affiliated with a p*rn site whatsoever!!!

statistics modules, which have logged everything of course...

you only can clear FE-Cache

first time around 16/17 march 2007. Always from different IP addresses. But
what strikes me, is that the most affected language is Chinese(Simpl.) and
just one or two URL's in Spanish/English... It seems to be a PHP problem,
but I really don't now IF it's TYPO3 or PHP or both...

it is a cache-problem, so every page and its parameter are cached, as far as
the cache is rebuild once a day, the first call to your pages may store
these strange paramters to the links from that page. (especially if those
paramters are defined in  "config.linkVars")

> So what I would like to know, has this been a hack attempt ? Or a script
kiddie? Or a spambot of some sort ?? Cause I have no idea...

I think it might be a try to hijack your site for  Cross-site scripting  or
SQL-injection (see wikipedia)

I like to know too
